A Pickin: BBC Four HD and CBeebies HD have moved to the COM8 mux which is on UHF channel 35 from Mendip.

R Nicholson: Digital UK predict no reception for COM5, COM5 & COM6 at your postcode, so you're doing well to be getting them at all. What signal strength and quality readings do you get on the COM5/ArqA channels? COM5 from Pontop Pike is on UHF channel 59 which is only just below the frequencies used for 4G by the mobile networks, hence the at800 filter. Is the filter installed before or after your amplifier?

Allan Cousens: Crystal Palace is one of the most powerful transmitters in the country and you aren't far away from it. Either you have a fault with your aerial/cabling/connections and are picking up some muxes from the flylead connected to the back of your TV or you could easily be suffering with signal overload (see the article "Too much of a good thing" on this website).

R Murchie: The new version of BBC Four HD is on COM8 (the one on COM7 is the old version which will soon be removed). COM8 is shown to be lower signal strength at your postcode than COM7. Can you receive the BT Sport Showcase HD channel on 115? What signal strength and quality does it show?

Robert August: 100% signal strength is too high and is effectively deafening the tuner. Does your amplifier have a variable gain control? If it does, try turning it down a bit. Where are you fitting the 4G filter? It needs to be before the amplifier, otherwise any unwanted 4G signals will be amplified along with the wanted signals. Retuning will never fix a problem with signal strength being too high or too low as the TV is already correctly tuned and all you are doing is deleting all your channels and searching for them again. Your PVR may have a less sensitive tuner than your TV and may be better coping with the high signal strength.

M robinson: Try a TV listings guide website. This site is for technical help with TV and radio reception problems and no one here any any scheduling information for any channels beyond what can be found in any printed or online TV guide.

Krysia : As the post above yours says, this is planned engineering work so the transmitter will be back on when the work is finished, usually by early evening. Do not attempt to retune.

R Murchie: The BBC don't decide the transmitter power and Ofcom don't have any say over which channels are broadcast on which commercial multiplex. COM7 & COM8 are temporary services which have been made available from 30 transmitters using 6 spare frequencies which were kept clear after digital switchover completed in 2012 and were brought in to use by reusing old pre-DSO transmitter equipment in order to provide additional capacity for HD channels on Freeview (if COM7/8 didn't exist BBC Four HD would probably never have been available on Freeview at all). It was always stated that coverage of these services would be limited to around 75% of UK households for reasons of cost and availability of clear frequencies. Broadcast power also has to be limited on some transmitters such as Rowridge (and various other transmitters near the coast) in order to avoid causing interference to existing services in northern France, Belgium, The Netherlands and Republic of Ireland. According to Digital UK, reception of COM8 from Rowridge will improve at your postcode when it moves to UHF channel 56 on 21st March, with further improvement early next year when frequency changes are due to take place at other transmitters.

J Whitney: Digital UK's prediction for your postcode shows a weak signal on COM7 and nothing on COM8 for Rowridge. Unfortunately it looks like you could loose COM7 too when it moves to UHF channel 55 in spring/early summer.

R Murchie: Have you checked for any loose or damaged cables or connections behind your TV? What signal strength and quality readings do you get on BBC 4 HD? Please provide a full postcode (the first half isn't enough) so that we can see where you are in relation to the transmitter and your predicted coverage etc.
